Ghostbusters (titled on-screen as Ghost Busters) is a 1984 science-fiction comedy film written by co-stars Dan Aykroyd and Harold Ramis about three eccentric New York City parapsychologists-turned-ghost exterminators. The film was released in the United States on June 8, 1984 and like several films of the era, teamed Aykroyd and/or Ramis with headliner Bill Murray. It was produced and directed by Ivan Reitman, who also directed Stripes, and stars Murray, Aykroyd, Ramis, Rick Moranis, Sigourney Weaver, Annie Potts, and Ernie Hudson. It was followed by a sequel, Ghostbusters II (1989), and two animated television series, The Real Ghostbusters (later renamed Slimer! And the Real Ghostbusters) and Extreme Ghostbusters.
